Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk of vehi-cle occupant scomin ginto contact with parts of
the vehicle's interior in the event of an accident.
The restraint system can also reduce the forces to which vehicle occupant sare subjected during
an accident.
The restraint system comprises:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securings ystems
The component softhe restraint system work in
conjunction with each other .They can only
deploy their protective function if, at all times, all
vehicle occupants:
Rhave fastened their seat belts correctly
(Ypage 41)
Rhave the seat and head restraint adjusted
properly (Ypage 74)
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (
Ypage 74).
You also have to make sure that an air bag can
inflate properly if deployed (
Ypage 43).
An air bag supplement sacorrectly worn seat
belt. As an additional safety device, the air bag
increases the level of protection for vehicle
occupant sinthe event of an accident. For exam-
ple, if, in the event of an accident, the protection
offered by the seat belt is sufficient, the air bags
are not deployed. When an accidento ccurs,only
the air bags that increase protection in that par- ticular accidents ituation are deployed. How-
ever, seat belts and air bags generally do not
protec tagainst objects penetratin gthe vehicle
from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags" (
Ypage 46).
See "Children in the vehicle" for information on
children travelin gwith you in the vehicle as well
as on child restraint systems (
Ypage 49).
Important safetyn otes
GWARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an
accidentort rigger unexpectedly, for example.
This poses an increased risk of injur yoreven
fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
component sortheir software.
If it is necessary to modify component softhe
restraint system to accommodate aperson
with disabilities, contact an authorized
Mercedes-Benz Center for details. USA only:
for further information contact our Customer
Assistance Center at 1-800-FOR-MERCedes
(1‑ 800‑367‑ 6372).
Mercedes-Benz recommends that you only use
driving aids which have been approved specifi-
cally for your vehicle by Mercedes-Benz.
Restraint system warning lamp
The function softhe restraint system are
checked after the ignition is switched on and at
regular intervals while the engin eisrunning.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp on the
instrument cluster lights up when the ignition is
switched on. It goes out no later than afew sec-
onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
Am alfunction has occurred if the 6restraint
system warning lamp:
Rdoes not light up after the ignition is switched
on
Rdoes not go out after afew seconds with the
engin erunning
Rlights up again while the engin eisrunning

immediately or open the window in order to pre-
ventbreathing difficulties.
Air bags and pyrotechnic Emergency Tensioning
Devices (ETDs) contain perchloratem aterial,
which may require special handlin gand regard
for the environment. National guideline smust
be observed duringd isposal. In California, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm .
Method of operation
Duringthe firsts tageofac ollision, the restraint
system control unit evaluate simportan tphysi-
cal data relating to vehicle deceleratio noraccel-
eration, such as:
Rduration
Rdirection
Rintensity
Based on the evaluatio nofthis data, the
restraint system control unit triggers the Emer-
genc yTensionin gDevices duringaf rontal or
rear collision.
An Emergency Tensionin gDevice can only be
triggered, if:
Rthe ignition is switched on
Rthe component softhe restraint system are
operational. You can findf urther information
under :"Restraint system warnin glamp"
(
Ypage 38)
Rthe seat belt buckle tongue has engaged in
the belt buckle of the respective front seat
The Emergency Tensionin gDevices in the rear
compartmenta re triggeredindependently of the
lock status of the seat belts.
If the restraint system control unit detect sa
more severea ccident,further component sof
the restraint system are activate dindepend-
ently of each other in certain frontal collision
situations:
RDriver'sa ir bag
RFront-passenge rfront air bag
The front-passenge rfront air bag is activate dor
deactivate ddepending on the personont he
front-passenge rseat. The front-passenge rfront
air bag can only deploy in an accident if the
PASSENGER AI RBAG OFF indicator lamp is off.
Observe the information on the PASSENGER AIR
BA GO FF indicator lamp (
Ypage 39).
Your vehicle has atwo-stag edriver's air bag.
Durin gthe firstd eployments tagethe driver's air
bag fills with sufficient propellantg as to reducet
he risk of injuries. The front air bag is fully
deployed with the maximum amount of propel-
lant gas if asecond deploymentt hreshold is
reached within afew milliseconds.
The activatio nthreshold of the Emergency Ten-
sioning Devices and the air bag are determined
by evaluatin gthe rate of vehicle deceleratio nor
acceleration which occurs at various point sin
the vehicle. This process is pre-emptive in
nature. Deployment should tak eplace in good
tim eatt he star tofthe collision.
The rate of vehicle deceleratio noracceleration
and the direction of the force are essentially
determined by:
Rthe distribution of forces duringt he collision
Rthe collision angle
Rthe deformationcharacteristics of the vehicle
Rthe characteristics of the object with which
the vehicle has collided
Factor swhich can only be seen and measured
after acollision has occurred do not play adeci-
sive role in the deploymentofana ir bag. Nor do
the yprovide an indication of air bag deploy-
ment.
The vehicle can be deformed considerably, with-
out an air bag being deployed. This is the case if
only partsw hich are relatively easily deformed
are affected and the rate of deceleratio nisnot
high. Conversely, air bags may be deployed even
though the vehicle suffers only minor deforma-
tion .This is the case if, for example, very rigid
vehicle partss uch as longitudinal body mem-
bers are hit, and sufficient deceleratio noccurs
as aresult.
If the restraint system control unit detect saside
impact or if the vehicle rolls over,t he applicable
component softhe restraint system are activa-
ted independently of each other depending on
the apparentt ype of accident .
RSide impact air bag and pelvis air bag on the
side on which an impact occurs, independent
fromt

seat belt usage
The side impact air bag on the front-
passenger side deploys under the following
conditions:
-BabySmart™ detect sthat the front-
passenger seat is occupied or
-the seat belt buckle tongue is engaged in
the belt buckle of the front-passenge rseat
